Manufacture of TFTR Toroidal Field Coils

A multi-year development and manufacturing effort was recently completed with the shipment of the last toroidal field (TF) coil for the Tokamak Fusion Test Reactor (TFTR) project. This manufacturing effort required the development and implementation of complex manufacturing processes and controls to assure TF coil integrity. This paper describes the manufacturing processes, tests and controls which were necessary to produce the 4.26 m OD, 22680 Kg copper TF coils for the TFTR.
